Phytomyza rufipes

Phytomyza rufipes Meigen, 1830

mine

The mine begins somewhere in the leaf, generally at the lower surface, not far from the leaf margin. From there a corridor runs randomly, until it hits upon a vein. Thd corridor then follows this vein until it reaches the midrib. Then the larva starts to bore into the midrib, and may descend into the petiole or even the stem. Pupation may take place either within or outside the mine.
